Stock OEM lifters or Aftermarket?

I'm going to replace my lifters and trying to decide between OEM ones or aftermarket

The OEM has the issue of possibly dropping the needle bearing. I wonder if the aftermarket is better or worse?

what kind of vehicle do you have and how many miles?

2006 6.0 114k I'm rebuilding the whole motor.

Stock, although roller lifters don't fail often. Although when they do it's disasterous. I'd never go with anything other than OEM considering a lifter replacement requires a COMPLETE engine disassembly. They are the LAST part to be removed!

If it where me, I'd inspect them for flat spots, wear, and verify the rollers all spin smoothly, and then re-use them. 114k shouldn't be an issue.

not if the idle time on the vehicle is way down. it seems like the ones that idle a lot or are severely neglected are the ones that are spitting out needle bearings

FACT. I just sold an engine to a gentleman that had a lifter failure. He had 9.999 hours on his engine, but just over 100k!

To the OP. As long as your average speed isn't below 30, I wouldn't be concerned about re-using the lifters. If you have a ton of hours on the engine, just replace them all!
