I think you lucked out and ended up with the best drone ever built for a great price.
No need for a Platinum unless color is worth several hundred dollars to you.
If you got a Spark, you'd just enjoy it and start saving for a Mavic, eventually.
A mavic is no more complicated to fly or maintain than a Spark - maybe even easier in some ways.
Stop over thinking it and enjoy it.
Happy Flying!
PS - don't fly indoors, watch lots of YouTube videos, be careful in Sport mode, don't expect the sensors to keep you from crashing into anything, don't fly too close to airports or people. You'll be fine.
Excellent advise! I could not say it any better. Watch the videos on Youtube, find your highest wire, tree, pole or bridge & set your flight height 10' above it - you will be fine!
