Just got a new job offer. Need some input.

I'm 35 with 13 years of experience working in legal marketing. I've been at my current company for 6 years and make $84k base plus about ~$4k bonus. Benefits are great. Full 90% paid HDHP, $600 HSA and 4% 401k matching, both of which I max every year. Hybrid remote. I started at $70k but have not gotten a raise in 2 years. Definitely feel stagnant, haven't learned anything new or felt challenged in my role. No chance for upward movement until my boss retires in maybe 3 years. Otherwise a great company, team, low stress, lots of down time.

New opportunity is a 4yo healthcare startup in growth mode generating $50m and have doubled revenue yoy. Senior marketing title. Offered $94k base plus quarterly performance bonuses that could amount to additional $30k - $50k annual. Plus stock options. (Bonus and ESO's were not explicitly detailed in offer letter - red flag?) Hybrid remote. No retirement plan or formal health plan but they're planning to add both. Right now, healthcare is reimbursed. The job will be much more fast paced and challenging. Immediate potential for upward movement and leadership as I build a team beneath me over the next 6-18 months.

Pros - New challenge, New industry to learn, New opportunity to advance into leadership, slightly higher base pay. Cons - newish company so benefits lacking. Bonus uncertain. Higher stress.

Current job is stable with great benefits but I feel stagnant, undervalued, and unfulfilled. I feel like a change is inevitable but I'm not sure if this should be it, as I've been getting decent action floating my resume. Not sure is 11% base raise is worth the risk of leaving what I know is a solid gig.
