Is sticking to the 2 year mark worth it even at a boutique firm?

So I'm a small ~30 person boutique M&A shop with a consumer focus in NYC - I recruited and made it to the superday stage 6 months ago for PE but since have decided against PE given it doesn't align with my longer term goals. I am at 1.5 years of banking and performing well (they want me to stay another year), but I don't really intend to stay in banking for the long term. Corporate/consulting seems more so aligned with my goals. Is 2 years of banking experience for a non-household name firm beneficial generally? I have a couple of legit deals on my resume at this point with large name sponsors and have had some good technical reps already.
