What type of ebike motor do i need?

Linked to another thread about buying an e gravel machine, was initially looking at a hub motor bike but have seen you can get one with a shimano crank based motor for similar price to what I'd spend on a ribble with a mahle hub

I'm thinking the pros of the hub based motor are lightweight and reliability, and much more like a 'real bike', whilst the shimano will provide far more range and I could potentially use existing wheels (ie if I wanted to upgrade or put a set of road wheels on there)

Is that about right?

Thanks
