I was wondering if a J5 tank could tank better than a J1 tank. I assumed it could, but could not find any confirmation through searches. All I could get for sure is that they were less likely to run. No one in chat over several days seemed to know either. So, I'm posting this for future searchers. The J5 tank is definitely better than the J1, and worth doing the quest and paying the extra plat to use them, at least to me. Here are a few of the stat differences between J1 and J5 at level 85, unbuffed: HP 17029 vs 30649 AC 1902 vs 2692 ATK 348 vs 581 STR 285+42 vs 325+82 STA 278+35 vs 288+45
