More is always better.
Get what you can afford.
I have not researched your options listed, but a good thing to do is pick the receiver that has all the connections and features you need.
Play with the remotes of each to see what you like.
Make sure the receiver has pre-outs so you can add more power later.
Invest your next money into a quality power amp on down the road.
Upgrade your receiver, or pre-amp, as needed.
The power amp can stay with your system as it grows.
