What are the best Fortinet alternatives?

Our shop has been pushing Fortinet for years but lately we're hitting some walls with licensing costs and support response times. Looking for alternatives that can handle 50-200 user environments without breaking the bank. We need something with decent UTM features, solid VPN capabilities, and ideally better partner margins than what Fortinet offers. Curious what other MSPs are having success with. What's working for you guys in terms of performance vs cost
