The other main options are tactile dome switches or mechanical key type switches, neither can offer velocity though (although not all silicone do either)

Silicone squishy type (aka dead flesh :laughing:) are generally very reliable and last well, they are also the easiest to fix.

Tactile dome are the least reliable, but cheap and easy to replace in most but not all cases.

Other options are capacitive like on say the Volcas, some of which can offer “pressure” sensitivity (really surface area, but fingers tend to squish!) and FSR type resistive pads - which is very similar to how silicon pads work, but they are comprised of layers of film with resistive element sandwiched between. These can be velocity/pressure sensitive but are often not very enjoyable to use, as they are pretty firm/rigid under the finger - a bit like drumming on a table.

For many use cases silicon squishy are the best option I think.
