The little bit of time I've spent in LE has been pretty fun (though I am first going to finish RDR2. I want to beat it!).
The Mako is pretty fun. It reminds me of the tweaks that are available on Nexusmods, it feels weightier. What does improve the vehicle over the mod for ME1 is the speed thrusters, making the vehicle faster.
The cannon is is ridiculously OP now that it uses hitscan. In ME1, the cannon could only hit targets its barrel could point at (e.g., no shooting enemies under you). Now, it can do that. On top of that, the lack of XP penalty for using the Mako means I don't have to whittle down enemies, get out, and get the killing blow on foot.
That being said, Thresher Maws need to be tweaked, imho. Their acid sprays are really pinpoint accurate, to the point that it feels like they have auto aim. It needs a minor nerf imho.
Honestly, LE made the Mako a lot more fun. It has the speed and tighter handling from Andromeda's Nomad (one of the few good things from that game), the power of the Mako from OG ME1, and no XP penalty for using it.
