If it aint broke, don't fix it!
If you have a working Fedora install, by all means continue using that.
IMHO SuSE is much more bug free and finished product than Fedora. I wouldn't recommend Fedora to anyone intending to use it as a production environment (even tho I use it on my work desktop myself (just can't be bothered to start over with some other install)).
Can't comment on your installation error if you are so vague.
