Coastal sailing chartplotting

Starting to gear up my new to me coastal sailboat and would like to put a smaller chartplotter on it. Been many years since I bought one and it looks like things have changed a whole lot.

Would love to hear the pros and cons of say OpenCPN vs Raymarine/Garmin/Simrad/B&G.

I'd like to avoid anything that would require a subscription. Really only need charts. Tidal current/tide table would be nice. Do not need weather/AIS/radar.

Smaller boat so don't need a big screen.

If you use OpenCPN what hardware do you use?

Thanks in advance
