All those are reliable peers and reputable LiSP, but not all have the same routing policies. Also routing fees could change from one day to another, so do not expect to be fixed forever.

But for example I would use ACINQ only in Phoenix wallet / phoenixd node, not with other nodes.

I suggest to NOT buy an inbound channel from Thor/Bitrefill thinking that in this way you will pay less routing fees when you use that channel to buy from the same Bitrefill. They are using intermediary decoy nodes for shopping on their page so your payment will NOT go through that newly bought direct channel. But that channel can be used to pay / receive to whatever other destination.
