My previous boat was a 21' Arima and it had an older Furuno 1870F unit on it for the MFD, though I'm not sure what transducer it had on the boat, and it didn't have radar on it. I wasn't a fan of the Furuno at all and pretty much disliked everything about it, though I didn't have the money at the time to replace the electronics and I sold the boat anyway, so I just left them as they were. I believe those units came out around 2012 or so, at least that's the year that shows up on the owners manual when looking online. Either way, I bought my 21' Arima in 2017 and even if the electronics were only 5 years old at the time, they still to me left a lot to the imagination. As mentioned above, I'm not a fan of buttons, rotary knobs or really anything else other than being a touchscreen. I know that not everyone likes only having a touchscreen in the event that you get water on the screen and it makes it more difficult to use. I've never really had that issue before, and most manufacturers make a touchscreen/button operated combination MFD to where you can use both or either. At the time I also thought that the unit/maps just felt old and cheap. I've admittedly always preferred Garmin brand of electronics as my uncle's boat before mine had a 12" Garmin touchscreen device on it as well as Garmin radar. I really liked his setup but that was back in 2013, so a lot has obviously changed over the years since that time. My current boat is a GW 228 Seafarer that came with around the same vintage, 2010, Garmin 7" touchscreen device that actually froze up while I was doing an update on it and upgrading the maps.
So, I decided to go with a Garmin 943xsv and really like just about everything about it. I like the touchscreen feature, it's a 9" screen that has great resolution, it's fast and it'll do everything and more that I need it to do. It's got the traditional, ClearVu and SideVu sonar, and I really just like everything about it. I know it's not exactly an apples to apples comparison when comparing now 10+ year old Furuno brand electronics to basically brand new Garmin electronics, but that's my opinion on the matter and the only relatable experience that I have with Furuno electronics. I don't have radar on my current boat, though I've considered it over the last couple of years since I purchased the boat in October of 2021. If I were to add radar to it, I'd likely get the Garmin Fantom 18x or something similar as I like the tracking feature on it for vessels, birds and so forth. That being said, in the 30+ years that I've been boating and fishing, I think there have probably been 2 times where I was ever in conditions that warranted the use of radar. One of those times I didn't have radar and the other time I did, of which it definitely was nice to have radar on the one occasion, but the other was just something to where I drove slowly back to our beach cabin, while paying attention to the GPS screen, depth of the water and all around us for other boats.
