That would depend on what purpose you use it for. Tier 10 armor is for PvE and Season 8 armor is for PvP. If you use PvE armor in PvP you will die very quickly, and if you use PvP armor in raids you will not be very effective. Stick to the armor type that matches the content you play in. If you "cross-dress" armor, consider it one season or tier lower for easy math. For instance, T10 armor would be about equivalent to Season 7 armor in PvP.
