GSPro vs E6 vs TGC 2019: which software is worth it?

The takeaway first: most home simulator owners should buy GSPro. It costs less per year than E6, its course library is bigger, and its physics and online play are the strongest of the three.

TGC 2019 wins one specific argument: pay once and stop paying. E6 wins another: it is the only one of the three that runs on an iPad.

Everything else is details. Useful details, though, because your launch monitor can change the bill.

What each one costs

Prices as of Oct 25, 2026. Software prices change, and your launch monitor may add its own fee on top, so check the software pages linked below before you buy.

• GSPro: $250 per year. One subscription, all features, all courses, no tiers and no course packs.
• E6 Connect: Home license $1,000 one-time for 27 owned courses. Basic subscription $300 per year with rotating content. Expanded subscription $600 per year for the full library.
• TGC 2019: $949 one-time for a lifetime license, sold per launch monitor family.

Three year math tells the story. GSPro costs $750 over three years. E6 Expanded costs $1,800 over the same stretch. TGC 2019 costs $949 once, then nothing.

Past year four, TGC 2019 pulls ahead of GSPro on price alone. Before that, GSPro is cheaper and more current.

Independent comparisons land in the same place on pricing, for example the GSPro vs E6 breakdown at Yardstick Golf.

Course libraries: big numbers, different meanings

• GSPro: 2,500+ community created courses, lidar based, free to download through the course server. Quality is high on the popular courses, and new ones land often.
• E6 Connect: a smaller, curated library. Basic rotates content through the year. Expanded opens the full library, and E6 has also been adding on-demand courses that stream instead of downloading.
• TGC 2019: 150,000+ user created courses plus a course designer. The number is real and also misleading. Quality varies a lot, and finding the good courses takes work.

If you mostly play five favorite courses, library size barely matters. If you like a new course every week, GSPro gives you the best mix of size and quality control.

Platforms: the quiet deal breaker

GSPro runs on Windows only. You need a gaming PC with a real graphics card. No Mac, no iPad, no phone version.

E6 Connect runs on Windows PC and iOS. It is the pick if your simulator runs off an iPad, or if you do not want to buy a gaming PC.

TGC 2019 runs on Windows only, but its system requirements are modest. An older gaming PC that struggles with GSPro at 4K can usually run TGC 2019 fine.

Which launch monitors each one supports

All three support the big brands, but the connector fee is where budgets leak.

GSPro lists 31 officially supported monitors, including Uneekor, FlightScope, Foresight, Garmin, and Square. Square and Garmin connect with no added brand fee. Uneekor owners need a Uneekor plan, and the new Pro+ tier at $299 per year now includes a GSPro subscription, which softens that bill. Foresight and Bushnell owners need their top tier plans.

E6 Connect supports 18+ monitors and is often bundled with a new launch monitor. If your monitor came with an E6 license, your starting cost may be zero, and that changes the math completely.

TGC 2019 is sold per launch monitor family through ProTee. Uneekor and SkyTrak owners still need their brand plan active to unlock third party software. Check your exact family before buying, because one license does not cover every brand.

Graphics, physics, and online play

GSPro, built on Unity, looks modern, and its ball flight model is the one most owners praise. Its online community is the most active of the three, with Simulator Golf Tour events running year round.

E6 is polished and easy to live with, with strong practice tools, 17 practice areas, and mini games that make it the most family friendly of the three.

TGC 2019 shows its age. The graphics have not had a major overhaul, development has slowed to compatibility updates, and ProTee has announced a successor called GolfCore. What you buy today is stable and huge, not new.

Our take

Buy GSPro if you have, or will buy, a Windows gaming PC. It is the best value per year and the safest long term bet of the three.

Buy E6 if you play on an iPad, if a license came with your launch monitor, or if family mini games matter as much as serious rounds.

Buy TGC 2019 if you dislike subscriptions on principle and plan to keep the same launch monitor for four years or more. Pay once, play for years, accept the older graphics.

Whatever you pick, price the full stack before you buy: the software, your launch monitor plan, and the PC if you need one. The software sticker is rarely the whole bill.
