The clearest difference is rating: Fly Go 4 at 4.1 against SIMREX GO's 3.3. Fly Go 4 also leads on update cadence (every 4 weeks vs every 2 months). SIMREX GO's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.

Fly Go 4 holds the better App Store score, 4.1 against 3.3. Both are backed by a comparable volume of ratings — 40 and 105 respectively.
