Your preference! I have had both. The aluminum boat has some great features such as, light weight, cheaper, requires less motor, less maintance, less worry about runnig her upon the bank in a strong storm. Glass is heavier for a better ride and is usually a little larger, this size does require more engine thus more fuel. constant cleaning, I feel safer in a bigger boat due to the fact I am getting older and less stable as I stagger around in the boat. I think your question will generate a lot of different views. For me bigger is better, so I run a 18 foot Hydra Sport with a 150 outboard. Best I have used yet.
