you are comparing the high end model of one mid-fi brand to a low end model of a high-fi brand. That sums up a lot of questions. It's about pricing and R&D strategy. Will VPI include the quality design and parts in the low end model and would Pro-Ject improve the quality of the Classic that much?
I would ask 3 questions:
- do you want to upgrade parts in the future?
- how do the needles compare?
- do you have any vibration issues?
I think the answers would give you good indication for which one you should pick
