Hi, this is my 2nd post (the 1st one is in the welcome & greeting center) 
I have a one year old metallic black car, paint is in relatively good condition. I wash the car myself once a week. Wax it once a month. Main problem are below defect water spot and very minimal of micro marring that only visible under the sunlight. I am a daily driver.
I use Meguiar's product. Some of them are:
UC, SwirlX, ScratchX 1, DC1 Paint Cleaner, DC2 Polish, Consumer Cleaner Wax, QD, UQD, NXT 2 Liquid, NXT 2.0 Paste, and several Supreme Shine MF.
I'm planning to buy a DA polisher, which is going to be my first DA. But I can not decide which DA should I choose. I'm planning to buy either Meguiar's G220v2 or PC 7424XP. I can see that both DA got a good reviews.
By using the DA, my goal is to eliminate the waterspot defect and the micro marring. Wax and polish it using my DA.
Can anyone help me to choose whether should I get Megs or PC DA. And moreover, which pad should I buy for my initial stock. I'm thinking to buy whether LC or Megs for the pad.
Thank you and your help is most appreciated!
