I recently bought an Aero 15. It's less than half a cm thicker than the new MBP and only 300g heavier. It's got a free SODIMM and NVME slot once you get the right screwdriver. There's plenty of reasons not to buy this specific laptop, but it's one of many that are in the same weight/size category that are both cheaper than the top end MacBook Pro and outperform it.
