I like them both. I usually buy generic wear parts like flipper rebuilds, bulbs, rubbers, etc from PBL and have only had one EOS switch that was too short that I can remember. They sent a replacement fast. I used to use PBR for classic games but PBL now seems to have everything needed for flippers.
As for flipper cranks, Ive had to spread some with a screw driver and squeeze some with pliers but never felt they didnt improve the game.
