Which do you prefer: Grab Bike vs Drive your own bike

I started driving a scooter the last few days and got used to how to drive in Bangkok quite easily. I haven't mastered quickly driving through tight spaces like Grab drivers, but driving myself is a much nicer experience because issues i've experienced with Grab drivers are: low quality bikes, terrible map skills (taking the worst routes), and just bad driving in general.

Despite all that, i'm considering going back to Grab. I don't enjoy driving since the roads are so busy it's actually annoying to sit in the heat without moving and also parking has proven quite inconvenient - sometimes places I want to go to don't have parking and malls require me to go down 3 floors to park. It's so much easier to just get off a Grab.
