I use a straight for my face 99% of the time. I find it more fun and enjoyable.
On my head I switch between DE's, Disposable straights and Straights.
I like my DE's, they give a very good shave, close to what I get from a straight.
One factor you would have to consider is the learning curve.
Straights have a bit more of a learning curve.
Once you have learned though, nothing beats a straight razor shave. IMO.

Both systems require much the same when it comes to prep and products.
If you start with the one, you'll be somewhat prepared for the other.

Price is another issue. A DE can be had for a song, and blades aren't much either.
Straights can be had for relatively low prices as well, but you would also have to get a strop and some sort of refreshing product, like a barber hone or a pasted strop.

It may sound as I am recommending DE's here, I am not.
But if you are to take on the straight, at least you should know what it takes!
