In general I think windy is still better by a small margin but both have pros and cons. Windy is especially better in isolated boss fights imo because fissure has some "blind" spots that dont hit enemies(maybe aside from andy because you can drag her through it). On the other hand fissure does make for better AOE if you are focusing more mobs like in TZ assuming you are playing d2r
Especially with sunderer charms now fire is more viable end game than it ever was before, so id say it depends on your farming plans and just whichever you think is more fun.
Just my opinion based on running both in pvm
