I think your standard Honda/Yamaha, etc. Inverter generator is probably just as good as anything out their.
It also depends on how much you want to spend or can.
An Inverter generator is going to be a lot quieter buy again its personal preference.
For me I want a generator that can power my 50amp TT easily and run on propane or gas.....yes its bigger, heavier, & louder.
I think you need to do a little research and pick the one that works for you.
I like this one below, but it's not for everyone.
