I've had both, and as other stated, there are advantages to both.
I currently have an aluminum and can feel just fine shoring it on rocks and leaving it out there on the shore even if it's choppy and overnight or for a few days. Glass ..... not so much, leave it on the rocks and in the chop a few days and you will be finding some swirl marks and stuff. But that's how I fish and camp and explore. If she was a dock queen or in/out every day like a weekend warrior - a glass boat would be fine too.
The MORE important consideration is getting the right boat for how you fish, where you fish, if you shore overnight on rocks often, etc.. and buying the BEST QUALITY boat you can afford. Aluminum vs. Glass will depend on this.
