If you're talking about V2, the Zealios 62 gr is closest to MX Brown. Not surprising, since it uses a similar spring weight. The 62 gr Zilents (Silent Zealios) are definitely closer to MX Brown than other weights.
Zealios have their tactile bump right at the top, with no pre-travel. Then, it's a fast bottom-out. The 62 gr Zealios are definitely more tactile than MX Browns.
If you're talking about V1 Zealios, on the other hand, these were more directly based on MX Clears, and were so smooth and grit-free that the 62 gr felt lighter than MX Browns to me, even though it wasn't. I think you had to go to 65 gr Zealios V1 in order for it to be more familiar-feeling to MX Brown users.
I've mostly been using Zilents, instead of regular Zealios. The 62 gr are just right, coming from MX Browns. Maybe even a little too light. 65 gr just feel slower and deeper than they need to, the 67s moreso. I wonder if 63.5 would be the ideal weight for Zilents, and maybe Zealios.
