Maybe. LispWorks may well be a nice IDE (I don’t know). However, its price is outrageously expensive!
For Professional Users, the price for the 32-bit/64-bit edition is $1,500/$3,000. Enterprises pay even more.
For Hobbyists, the price for the 32-bit/64-bit edition starts at $500/$750. (There’s a free Personal Edition available for evaluation purposes, but it is extremely limited in usability.)
Pharo is free. Squeak is free. Dolphin Smalltalk is free. Even Cincom has a free Personal Use License edition without any technical limitations. I like free.
Maybe this is why Emacs/SLIME is so highly recommended.
