Seimitsu vs Sanwa... buttons

Well, having recently practiced with an all Sanwa stick I wondered: just how different are the buttons. I mean, I could feel quite a difference to the standard Hori buttons, they were much shorter and had a better hitting feel to them.

But those Seimitsu buttons look great so I wondered, would I feel a big difference if I swapped my buttons for Seimitsu ones?

No excuses for this shit
