Stay where you are and get your command. The aviation world is extremely volatile (especially at the moment) - if you leave without command time you may find it difficult if not impossible to get back in again. In the UK, you will be competing with all the pay-for-a-job newbies (as you know working for Ryanair), so your only options may lie abroad. But - many of those jobs require currency within the last 12 months for licence validation purposes which you might not have so you would be effectively shut out from those jobs. If you are lucky and manage to join a legacy carrier you may never see a command in your career due to lack of growth and many, many pilots ahead of you waiting their turn in the seniority system.
Getting the command first gives you options and protects your future.
