What is better, analog or digital?


I'm listening to the Best of Marley on the album, and I have to say it sounds better then digital.   More definition and more realism.  Of Course this is MHO  Using a Rega Planer 1 w a cheaper Project phono amp.  

 Let the debate begin, and what should i change out first for better sound

It really depends on your system. I listen to both formats, but vinyl sounds better in my system. 
OP says " Let the debate begin." Members like him that start this same thread 1000 times over never let the debate end. Talk about BORING. 
A diamond needle riding the undulations in a spiral groove on s rotating plastic disc - or an ADC measuring the voltage variations of a microphone signal/ magnetic tape? Each can be made to work well!

You answered your own question: change out the cheap phono stage.
