Most Islanders ( mine included) have ABEC 3 bearings and work perfectly. Most guys who upgrade go right to ABEC 7... you'll have a tough time finding ABEC 5 Islanders.
I've never fished the T-5 but I know you can't go wrong with the Islander. It works well in all weather conditions, easy to take apart and clean streamside if necessary and it will withstand more abuse than a lot of the really " tight tolerance" reels.
Like Porkpie said, if you want to spend T-5 money, get a reel made by one of Ontario's fine reel makers. I've got a Canada Drifter ($525 tax in)...beautiful looks, super smooth, you deal directly with Wayne, a real (reel) gentleman...and I guarantee you won't be bending it on any salmon...
