They're all "good" in one way or another.
Some are good & cheap.
Some are good and fast.
Some are good and stable.
Some are good & expensive.
Some are good & welded.
Some are good & riveted.
Some are good & all-around good performers.
Sea Ark, F&F, War Eagle all build good boats, but don't forget G3, Excel, Weld-bilt, Alweld, Waco, alumacraft, Havoc, Edge, Vexus, Ranger, and a ton of others.
They all build decent boats, just depends on the use it's going to see, how much you're willing to spend, what features you want or dont want, how fast you want to go, etc etc.
Spent the afternoon messing with a Ranger VX1888, well more working on the 225 Yamaha outboard than anything, diagnosing intermittent issue. I loved the boat but it's way too big for what I'd use it for. There ain't no way I'd own it unless I was strictly fishing the deeper lakes with good ramps. I mainly stay in shallow rocky rivers and occasionally the lake but back where the sunlight's got to be pumped into-which a bigger boat ain't gonna get to unless a helicopter picks it up & carries it into the 3'+ water. The ranger I was in today was dragging bottom slightly in 24" of water which ain't cutting it for what I do. I'd have the foot drug off of it in less than 30 minutes.
One could spend $1000 on a cheap riveted jon, or one could spend $100,000+ on something with a cabin, etc. Take your pick...
I've had a lot of different setups. In the early 2000's I bought my first 1432, built a deck for it (mistake!), carepeted the whole thing, floored it, and built livewells, etc for it. Went tournament fishing on the local lake. 9.9 OMC. Wouldn't plane the boat with all the weight I had in it, but it's all I had and I used it for a few years. Saved money, sold that one, updated to a used Duracraft 1542 riveted jon. Just bare, and left it bare with no seats. 25hp Evinrude. Did what I needed but it also did MORE than I wanted, in leaks. Every time I'd buck a rivet, another one or two or dozen would leak. Finally sold it and bought another one just like it, built by Noah (Duracraft), all welded 1542. It was ok but outgrew it, and it rode really rough with a totally flat bottom. Also would not take wake very well, wouldn't even take chop without getting wet which wasn't a problem in the hot summer but any other time of year it sucked. Sold that and bought a 'glass boat with a 90hp Mariner. Spent more time fixing things than I did fishing, and it drafted way too deep to be useful. Sold it, bought a 1542 Grumman with a 25hp Yamaha 4 stroke. Originally bought it to re-sell but liked the motor so much after running it that I hung onto it for a while. The boat wasnt' great but it fished well. Just too light, rode horrible, spun in turns, etc. Sold that boat for $200 more than I paid for it, and kept the motor, bought a 548 war-eagle and still have it. Kept the motor on it for about 5 years, guy made me an offer I couldn't refuse, sold it, bought a new yamaha and still have it. It does everything I need it to and nothing that I don't want it to do. Complaint? Low casting deck gets hot, but hydroturf fixes that. I pull it out in the spring/fall/winter and put it back in for the summertime. Rides great, dry, handles decent, reasonably fast (enough for us anyway), motor sips fuel, goes everywhere I need to.
