For a rack top bag I would go Racktime (which is owned by Tubus) it is an aluminum rack that is compatible with a whole host of neat bags, baskets, and panniers (MIK uses the same bolt pattern so if you find a MIK compatible bag you can adapt it to Racktime). Plus Racktime does dynamo and e-bike compatible racks with lights on the back which is nice. If not them Topeak makes a fine around town rack.

I personally am quite happy with my Tubus Cargo rack and if I was doing it again probably would have gone Logo but honestly haven't really had major problems but I don't tend to run a rack top bag and panniers (I have Arkel GT-54s so plenty of space) I usually strap down sandals and other random stuff that doesn't need a ton of space or is semi flexible.
