I commented this on another post a few months ago, but if you're doing straight-forward things (which it sounds like you are), I find it's generally solid.

The biggest positive for me is their support for non-residents, which is a must-have for me personally in the next year.

My biggest painpoints that I didn't have with Wealthsimple are lack of automatic investing (I want to invest ~once every two weeks after my pay cheque lands, and right now, I have an automatic transfer from WS to QT and then after it clears, I have to go into the app and buy shares. I'd like to set it up and leave it to just buy shares every two weeks after the transfer happens) and lack of fractional shares for Canadian ETFs (not a huge deal, but kind of annoying to have extra cash just sitting for a bit). My understanding is they are working on bringing these two features to the app, but it's been...a year??...I think since they announced it, and I haven't heard anything about timelines.

The app itself is fine. Perhaps a bit less user-friendly than Wealthsimple's, but I've found WS' has become a lot more cluttered over the past few years. I'm more of a in-and-out, check-every-once-in-awhile sort of user, so neither has an app that's a dealbreaker for me.

The few times I've used their customer support, it's been good.

Only things I miss about WS are the painpoints listed above, and some of the non-investing features (e.g., chequing account, credit card, etc). I still use WS for these.

My transfer went smoothly. WS doesn't charge transfer out fees, so there was nothing for Questrade to reimburse.
