What are "White clicky tactile alps" and what are "green alps"?
"Alps" switches are switches made by Alps Electric of Japan, or subcontracted products with Alps branding. I class post-Alps (de-branded) SKBL/SKBM ("Fukka") switches made by Forward Electronics of Taiwan to be "Alps" as the switch series started off with Alps branding. If Alps did not make it or licence their name to it, IT IS NOT AN ALPS SWITCH!!!
Seriously! It's like calling Chinese Cherry MX clone switches "Cherry" switches just because they look similar.
White complicated Alps (SKCMAQ/SKCMCQ) were discontinued around 1996. White simplified Alps (SKBMFA) were discontinued in 2012.
I don't know what's inside that Solidtek — it could be old-stock Alps, Hua-Jie AK-CN2 or AK-CN2 (2), Xiang Min KSB-C, APC BSW series, Datacomp, "YH-B", or another Alps clone we don't know about. Post a switch photo where the branding/numbering is clearly visible and I'll give you a good idea of what it is.
"Green Alps" typically means the old Alps linear switches from the early 80s; Alps also made a tactile switch with a green slider, and a very strange force curve.
Mint green is also a popular colour for clone switches, but the colour has no defined meaning. Ducky "green Alps" is a reduced-weight Xiang Min KSB-C, while my KSB-C samples are ivory. Xiang Min colours are a mystery. Green means something different to APC BSW Alps clones, and different again to Himake and Hua-Jie Alps clones.
To answer your question, you need to be specific about which white switches you want to compare with which green switches, but even then, I couldn't give you a clear comparison due to lack of product consistency with clones.
