Want to upgrade my cartridge from 2m blue to black

The 2.2 can certainly benefit from a better cartridge. I'm not familiar with the Ortofon cartridges, so can't say how much of an improvement the specific upgrade you're thinking about will make. I have a Nagaoka mp500 on my 2.2 and it sounds really nice. I wouldn't spend crazy money on that table though, you might be better off spending that money getting a 5 series or 7 Series Music Hall second hand and putting the cartridge you have on it. My 5.1 sounded better with a $50 AT95e on it than the 2.2 with the mp500 on it. 

Better table first.

Yup, most definitely table first and phono stage second.

 I’m definitely an analog lover but am budget constrained. Any feedback will be greatly appreciated.

It seems like other folks ignoring your statement about " budget constrained", cartridge is the most important in your situation, change the stylus profile first, this is the most cost effective solution to upgrade the quality. You can always use your upgraded cartridge on another turntable. 

I have a local friend with similar cheap belt drive, he changed M2 Red to Stanton 881s mkII and it was huge improvement in sound quality without changing anything else, later he has bought a better phono stage, but still using the same turntable (Pro-Ject). 

Chakster, Where is the OP gonna get a used 881s with a good stylus? There's a couple on eBay of unknown quality. While I acknowledge the quality of the cartridge, it's not really viable advice.
