2015's CLisp implementations: Where can I find them?

As new CLisp implementations like Clasp appear, I wonder if there is a decent feature (not just *features*) comparison between them available. The CLiki basically lists licenses and names, but it's still more or less a "download them all!". Is there a user group actively working on a "real" comparison in Wikipedia's "Comparison of ..." style? If not, I'm willing to start one.

I recently switched from SBCL to Clozure for no good reasons and I'm positive to switch to Clasp some time for no good reasons again. I just want to know what I'm doing.

There is a kind of comparison, lots of text fewer tables. It could be out of date, I haven't inspected that.

I found that one to be quite useful, but it doesn't have Clasp (and probably other implementations are missing too).

The ANSI Common Lisp Standard hasn't changed since 1994, so there are not much "new" things to miss. AFAIK Christian Schafmeister's Clasp is the only new Common Lisp implementation since Dan Weinreb's Lisp Survey in 2010.

Here a list of things I remember from the last few years that are not covered by the Lisp survey:

• Clozure CL (CCL) - Zach Beane (quicklisp) works now at Clozure Associates.

• Corman CL - has been open-sourced in early 2015, see this post here in the Lisp forum.

• Embeddable CL (ECL) - Juan Jose Garcia Ripoll has stepped back as the main developer of ECL, which is now maintained by Daniel Kochmanski and a group of other volunteers.

• GNU CL (GCL) - has been resurrected by Camm Maguire in 2013. There have been some new releases since Dan Weinreb's Lisp survey.

For me on OS X clozure lisp has been the easiest to use. I assume if one can afford lispworks hobbiest edition that would be better. I believe clozure works on windows too.
