Hey @benx if you’re looking for neutral, clear, and analytical then that would be the Olina or ER4XR. I also just recently did a comparison between the Olina and ER2SE here: 🔶 Tripowin X HBB Olina - #1524 by VIVIDICI_111
Timeless and Olina are about even in resolution, but Timeless sounds thin at times due to the planar driver and probably has more bass than you’d like. Olina is too bright at high volume but that can be fixed with an easy mod as mentioned in the review.
S12 has similar detail as the Timeless and Olina but is sibilant and can’t be modded unlike the Olina.
I’d avoid the FH3 personally since it lacks in resolution and imaging compared to the other two, and the Olina is just a better version of the Kato at half the price after mod.
Edit: Not sure regarding Aladdin anymore 
Personally my pick would be the ER4SR or the Olina 
ER4SR is more neutral where the Olina is neutral-bright. Both are very analytical and clear with one of the best timbre under $200 imo.
