Well...what do you mean by electronics? AIS, RADAR, VHF, GPS, Chartplotter, Depth, Speed, Wind, Autopilot?
Going with a system that uses/supports NMEA 2000 would probably be a good idea at this stage of the game. It also depends on your budget.
I'd point out that Raymarine is currently in transition, as they recently were bought out by FLIR, and availability and support may be an issue with them during the transition. I know that getting some parts from them has been very difficult, depending on what it is.
Garmin doesn't make a sailboat autopilot AFAIK
, but their gear is otherwise quite good, and their chartplotters are more intuitive than most other brands. Their radar, the 18HD is pretty well regarded for a lower cost unit, but doesn't have the features that some of the higher-end Furuno and Raymarine units will have.
TackTick makes speed, depth and wind instruments, but little else. I have and like their wind, speed and depth instruments, and would point out that they can interface with other brand gear via an NMEA 0183 interface, but it is a dated interface that will be soon obsolete IMHO. If you need an autopilot, chartplotter or radar, you'll have to go elsewhere.
