If you mean Gibson
vintage reissues, I recommend them. I have a pair in my ‘97 Gibson’ bird. I bought these directly from Gibson when they came out with them, and they are really well balanced, plenty of bottom and great definition. There is no differentiation with these pickups when you buy two at a time. My recollection is that they both say “lead” on the sticker that’s on the bottom.
I have since acquired (twice) pairs of the vintage reissues that came from 2021 Gibson NRs. These sets are designated “Rhy” and “Lead”, and the lead one reads higher on the ohm meter than the other. I have these in my 2014 Cherry, and these also sound very similar, but I have the instruments in different tunings and different strings, so a direct comparison is not possible.
This is a pic of one of the used 2021 NR sets that I got:

The ones you can buy from Gibson will be the top one “Lead”.
