CMUCL, because it's solid [IME], has a good compiler, and its
interpreter's design means that it's good for "scripting", too:
it starts up *fast* [slightly faster than CLISP, actually, on
the machines I use], and its interpreter does lazy analysis of
DEFUN bodies [which is good if you have large scripts with a
bunch of DEFUNs only a few of which get called on any single
script invocation]. Its "green threads" are also well-integrated
with standard CL stream I/O, and give you automatic non-blocking
I/O when running multiple network connections at the same time
[e.g., when using it as a web application server].
It has some downsides, but none of them currently affect me:
- Only has "green threads" [user-mode coroutines], so threading
only uses a single CPU, and that only on the x86 platforms
(Linux & BSD, mainly). [But all the platforms I currently
run it on are single-CPU, x86 Linux or BSD.]
- Doesn't (yet) run on Windows. [But I don't do Windows.]
- Rebuilding is a bit tricky. [But I tend to run the "-RELEASE"
binaries without ever rebuilding.]
