I've had a bunch of aluminum boats, including 3 Lunds. I have also had 3 glass bass boats (Rangers). Many people comment that they downsize boats to something that it is easier to manage by themselves. I've never quite understood that - unless you are talking about using very shallow ramps.
If you are using ramps where you can float your boat off - the glass boat is just as easy to launch as an aluminum boat. And if you can float your boat off you should be able to drive that glass boat on your drive-on trailer in about 5 seconds and step off.
With the right adjustments and accessories aluminum boat trailers can be made almost as easy to use - but wind and current can be a much bigger pain when loading an aluminum boat.
IMO the only advantage an aluminum boat has in the "ability to manage with one person" department is that you can nose it up on a rocky shore with less worries than a glass boat.
The primary advantage of an aluminum boat is that it can be used in much smaller water with shallow ramps (which is why I'm using a Lund to fish from these days), is cheaper to run, and cheaper to tow.
In the multi-species department, deep-v's often have an advantage. Trolling is often easier in a deep-v - especially if your bass boat has a 200hp and no way to hang anything else on the transom. I replaced one of my Rangers with a Lund because I was spending a fair amount of time trolling for salmon and trout, so I wanted a smaller motor to troll with, and was doing some striper fishing and didn't wanted to dunk my RangerTrail in the salt.
But bass tournaments were not quite as much fun in the Lund due the boat being much slower and less stable on the water. As stated above, the deep-v does make it a much bigger pain to use in the wind and the lighter weight means they get bounced around a lot more than a glass boat. (That may not be the case with the big heavy 20'+ pro-v series.)
I brought my kids up bouncing between Rangers and Lunds, and I don't necessarily agree that one is safer than the other. Make them wear life jackets.
Sure, they are less likely to fall out of a deep-V when fishing in calm waters, but if the water is rough and you need to get off quick when real danger is present, then a heavy stable glass boat is the safer option in my experience.
I like both and having been bouncing back and forth between them for 20 years.
