actually they're both almost the same specs for modding
there's no more extra hassle with working on the cheaper horis now since they have mounting screw holes for a JLF with a plate, the only hard part is desoldering the hori buttons
The SE however is just drop in replacements, no extra work necessary
as good as the SE is, if i had a choice of the two, i'd choose the hori over the two since i like a slimmer and somewhat wider stick
