Hi Nistrum.
Talk about a can of worms! EVERY modeller you'll ever talk to has an opinion on the acrylic/enamel question. You'll find certainly hundreds and possibly thousands of comments both here and on other modelling sites discussing this.
I'm happy with my
Revell Aqua paints - although I am going to get alternatives for their metallics. But there are guys out there who wouldn't use acrylics to save their lives. Only thing I can say is try what you've suggested. If you're not happy experiment with alternative acrylics. If you're still not happy give enamels a go. You may find you'll use both for different applications.
Mind you, my prejudices are showing here. I'm only suggesting you try acrylics first 'cos they're what I use - and I prefer them because they're easier to clean up!
The more you look into how models are painted, the more opinions you'll find. It starts with prime/not prime as you've already asked. Then it goes to brush/spray, then acrylic/enamel. Then it moves on to weathering. Oils/water based/pastels, brush/spray etc. etc. I've seen truly awesome paint jobs done using all the different methods. I guess it's down to what works for you.
