OK that's a bit more like a reasoned debate

. People who fly PE in their droves seem to think it is good value for money. If your sole experience of flying is charter then it is unlikely you will. If you have experience flying other carriers then you'll realise they operate as close to a cartel as they are legally allowed to do - meaning there isn't much difference in costs for size of cabin provided in Economy and "Economy Plus".
Now the majority of people here love flying with VS because of the crew. You seem to have had an experience that is at odds with this. If you check
this link here you'll see that the average of hundreds of trip reports is that the crew are better than good but fall short of excellent. This naturally begs the question why? A lot of people react to how they are treated by others and VS crew are human too.
To fly on an airline because their aircraft are newer, is, in my opinion a very strange basis on which to choose an airline. The majority of people seem to go on safety record, quality of service etc etc.
To summarise - to see what other people think, check out the link above. Regretfully the opinions expressed there don't accord with your own but you have that right.
