there s no"equal" between them.HT is waay better than jade coz HT has fakin good defence overall and leaderboards not mix with them... 90% HT.period.
An EU player has cleared GR96 with Jade - and with less than 1500 paragon (the NA #1 clear with HT was with 2230 paragon). So yeah, that is pretty much equal. That more people play HT is just crowd mentality which we see all the time because only 0.1% of Diablo players actually think about non-FotM builds (despite claiming they want diversity).
Interestingly, even Arachyr has cleared GR93 (Yoda on NA) - which is #4 on his region and #20 world wide. So even that is a potential answer to OPs question. Note: He didn't ask for "what's the flavor of the month build that everyone and their dog is running". He asked for which builds are "strong at end game". Given the evidence from leaderboard, HT+Jade and to some extent even Arachyr have to be named here to give a true, objective, and unbiased answer to this question. I have no idea about Zuni and LoN builds, would be interesting if someone has cleared 90+ or 95+ with those (I know it's not showing but someone with a 91+ HT clear could've cleared 90+ with Zuni just a tier lower).
Saying it's 90% HT just reflects that 90% of the leaderboard is just following a popular build, but it says nothing about true powerlevels. We've had this every season. My prime example is always Season 3, 4 player, where everyone was assuming that DH was top DPS when in fact wizard was clear #1, but even top groups didn't switch in time, which resulted in a leaderboard that didn't show the "best" build composition, just the "most popular".
why ht is better:if u wanna go like gr 85(i assume u aiming dat lvl) u gotta fish with other sets 10 but with ht 2-3. this means ht is not only most popular set but also ez to reach ur goals without too much effort. Also waay more defence and less stress than jade. Ppl just trying to show off that they can make leaderboard with jade or with other sets. After makin it asap they return to ht. U can t see in public with jade or any where else but only places that i mentioned above. Think like this: gr 90...10 trials with ht, 10 trials with jade. Ht beats jade ass up most of the trials.
