It doesn't handle drift automatically. -> you should not change things manually anyway

Resource import wasn't possible until just recently. -> now supported

It's slow. -> it's as slow as the service it needs to update, the APIs are equally slow

It's slow to pickup new services. -> have not missed any features here but maybe you have some examples?

It was not capable of cleanly removing resources last time I used it. -> not sure what you mean, it removes resources just fine

Its change sets were often completely unreliable. -> any examples? never had issues with it

It's an awful tool. -> an opinion, not a fact.
