Pulled 2 Reinhardts, both decent. +Atk/-res and +def/-spd. I dont have access to a distant counter so enemy phase tank probably wont be feasible. Which direction should I go?
+Atk/-Res works better for Player Phase since Rein aims to hit and kill harder, whereas +Def/-Spd leans towards for Enemy Phase since he'll be a bit more bulky.
Edit: On that note, having a bane on Spd is actually good considering how slow Reinhardt is on the first place and also seeing how you'll get to attack twice regardles of whetever you're on the assault or defense thanks to his sword.
Overall, both are manageable options.
You don't need Distant Counter to have a good enemy phase tank, you just need someone that has good defense and/or resistance.
With that said, both of the IV sets are fine depending on what you're trying to do. Like previously stated, +Atk/-Res is better for a Player Phase build whereas +Def/-Spd is better for an enemy phase build. If you're looking for an IV set for both phases, then +Def/-Spd is probably the best option.
