Most people have a built in bias to stick with what they know rather than trying something new. We probably stay in bad situations much longer than we should. Ymmv
That's totally fair as well. Although things worked out pretty well, I have stayed at long-term jobs for longer than I probably should have.
One key is probably to really ask yourself why you want to make a change (or why you're hanging around if you don't really like the situation). If you have good answers, that's fine. If you don't...
Ultimately you have to make decisions based on incomplete information and with the knowledge that no situation is likely to be perfect.
