Learning SEE might be easier in the short run but long term it will hinder your learning ASL. You will have to "unlearn" a lot of SEE before you can learn ASL, and that will just confuse you and slow down your acquisition of ASL. It's better to learn ASL first. You can always add SEE signing later if you need it for educational interpreting. In fact, my terp program taught us ASL interpreting first, then SEE transliterating second. As a terp, you should eventually learn not just ASL, but SEE and PSE/MCE so you can provide your clients with whatever mode they prefer.
