For this level of gear, I can’t imagine not looking at Taiko, Pink Faun or the Antipodes Oladra. Those are the best of the best in terms of servers that are not brand specific like Wadax. The choice should be driven by what input you plan to use and the best way to get clocking to synchronize.
I would have to contact Antipodes or Pink Faun to determine optimal method for connection as I am not sure the best way to ensure optimal clocking. Same with Taiko but I don’t have a direct line of communication with them like I do the others.
