Commercial Lisps are better? As in faster?
Do you have any supporting evidence of this?
Having used Lispworks and Allegro I can't see where this is coming from.
fpm would solve their "packages are hard" problem.
Additionally, when the upgrade path is "curl|bash" that is poorly thought out.If "curl|bash" installed the package repository, and then used the local package system to install, then that would be better.
