..none of your post seems to be to do with a static up address apart from the subject.
They are not 'good' or 'bad' just different options depending on what you want. With static I suppose you can register a dns name to point to it, but you can even do that with dynamic. Static is good if you want to setup a VPN or some sort of connection where the other end knows your IP address and you don't want it to change.
For day to day web surfing I don't see it being any difference.
It certainly won't impact your speed or anything else you mention.
