While I'm not the best playter around, I prefer forward focus type since I'd rather muscle my way through bosses than take my time with them. Obviously I still need the skill to survive long enough to kill them, which is probably part of why I'm not very good...
Of course, the stage difficulty also plays in, because I have to dodge a lot more and generally focus on priority threats. It generally takes a lot of practice no matter what I do, but once I memorize everything it gets a lot easier, and above all else I'd rather have boss fights not get drawn out, because if they do I know I won't be able to keep up my dodging consistantly...
Also, I usually prefer the laser variety of power types for the pierce ability. This way I can minimize threats of enemies that are in a line, and small fry get in the way of my aforementioned priority targets. As Marisa might say, why let something as trivial as enemies or destructable shots get in your way?
