XCOM 2 is pretty manageable on L/I.
The only hard things are Gatecrasher and the first Retaliation and you can technically fail it and be fine(ish). After that Mag weapons are in sight.

Now XCOM 1 on I/I is just groin abuse at the start. Even the devs admitted they made it bullshit since they didnt know how to make it harder any other way. 6HP thin mints are just pure rape until lasers and even then they'll fuck you at times.
