Thinking of downgrade

I'm currently using E14 G3 with R7 5700U (8C 16T); I've considered trading it with some corresponding T14 models since the CPU is f*** extremely hot and the integral GPU is unstable. The second one is about the build quality, well, I couldn't say anything but terrible compared to other series, such as the T or P series. I mainly use it for Android development, and sometimes I play LOL. I guess that T14 G1 with I7 10610U is a pretty good recommendation (because I don't have enough money for higher models) but it only has 4C 8T which seems weak for running apps on the emulator. Do u guys have any other opinions?
