Should work good either wheel. I ordered a used G25 recently, and I am currently using a Logitech DFGT.
In the title you say G25 but then you talk about G27... But anyway, I have a G27 and it works just as good as you would expect.
The G25/27 should work very nicely with BeamNG. The G25 probably has the worst FFB system you can put in a wheel, but it works.
i would chose a G 27 but the G 25 has the choice between H gate and sequential and that beats farther apart pedals for me
You get much better FFB with a G27. The only reason why I didn't buy a G27 was because there wasn't one available in the 250$ price range at that point in time.
