It all depends on what I'm doing... If it's a script that I'll use more than once, I tend to lean towards readability. If it's an obfuscation, I go for confusion of course.

For what should be obvious reasons, these are some of my personal favorites:
s@{.*?}@{$sub[$n++]}@g;
s${.*?}${$sub[$n++]}$g;
s%{.*?}%{$sub[$n++]}%g;
s={.*?}={$sub[$n++]}=g;
