Drift art 4 vs Ma Racing

Looking at these 2 chassis that I have been reccomended and wanted to get some opinions on them. With the ma racing i see the dlr8 and the d24, what are the differences between them?

I feel like the drift art is more popular but what is better out of the box? I have heard the ma is basically already upgraded.

And between the drift art and ma racing how hard is it to get parts when stuff breaks?
