It's interesting that this user was using notmuch before Gnus. I switched notmuch.el+notmuch to Gnus+notmuch last year, i.e., I kept using notmuch but I switched from notmuch's own Emacs frontend to Gnus's support for notmuch.

It takes Gnus ten minutes to start up even with nativecomp, and hours to do its initial indexing (but you already have to give up that time for notmuch's own indexing). It's unusable without nativecomp.

I switched because I realised that I was hackily reimplementing many Gnus features and ideas on top of notmuch.el in my Emacs init. I had to fix some bugs in Gnus, and help the author of nnselect fix some much harder bugs, over the past nine months. It works well now.

Wow. For me, Gnus starts in <10s. But I guess it depends a lot on what backends you use (I use dovecot+mbsync for mail, so Gnus doesn't really index anything)
