64GB DDR4 RAM vs 16GB of Unified Memory? Trying to decide about switching from Intel Mini to M1 Mini

Hi. Here's my situation:

In April I bought a 6-core i7 Intel Mac Mini and upgraded the RAM to 64GB. However, now I'm regretting buying the computer after learning about how much more powerful and efficient the new Apple Silicon Mac Mini is. I'm very tempted to try selling my Intel Mini to then purchase the M1 Mini. If I decide to sell, I want do it soon while the Intel Mini still has some value; I fear fairly soon that its resale value will plummet.

The only possible reason I can see for keeping my Intel Mini is that it has four times the amount of memory as the M1 Mini. However, I know the M1's unified memory is faster and I've heard that applications optimized for Apple Silicon use memory more efficiently, just like apps on iPhones and iPads do.

I also have an application on my Intel Mini called iStatistica Pro that shows my Mini's memory usage. And generally it shows that I'm using up to about 24GB of RAM from running applications and have about 10GB to 20GB of RAM being used as cache.

So my questions are: are there any advantages to the larger amount of memory on my Intel Mini vs the smaller amount on the M1 Mini? Is it true that an M1 Mini could run significantly more applications if they are all optimized for Apple Silicon?

Thanks in advance for all replies.
