Alrite stressy!
P.S
I want my battery back

You can have it back so long as my battery is charged like I charged your one lol!
There are no best headlamps too be perfectly honest. Reason I say this is, I myself, GTiadam for example love the Hella Twins, others will prefer the angel eyes, plenty of other people would prefer to have standard lamps, or a modded standard lamp smoked or similar.
As mentioned, if you want to run HIDs you need projectors or you're going to blind everyone, and make yourself much more apparent to the police who will inevitably pull you and fine you. HIDs are illegal in any car that doesn't have washers, self adjusters and projectors.
Even running them in Hella Twins is still illegal, and will 99% fail your MOT (some will get away with it depending on test centre).
