Bitcore full node list with Wallet service enabled?
Nodes don't provide wallet services (like Bitpays Bitcore [don't mix that up with Bitcoin Core]). The only service they provide is SPV transaction filtering (which is much "slower").

Running your own wallet service (like BitPays Bitcore) can be useful if you have your own setup, etc. (It's more a server/client thing).

Bitcore is basically a Bitcoin Core full node with some extra database layers (address index, etc.).
The full node behind Bitcore will connect to some dozens other full nodes (p2p).

You don't want to manually maintain a list of full nodes. There is a built in p2p address manager.
