DF64P SSP burr upgrade vs DF83V? Worth it or just an upgrade itch?

I’ve been using a DF64P for about 3 years paired with a Quickmill Aquila (rotary pump HX machine), and overall I’ve been able to make great coffee with it.

That said, I’ve never loved the grinder after some longer-term use. My main complaints are:

• The vertical design, no tilt or auger
• The workflow is messy
• Slight “budget grinder feel” compared to the rest of my setup

I’m considering two options:

Option 1: Keep the DF64P and upgrade to SSP burrs (Cast, HU, or Lab Sweet — still deciding)
Option 2: Buy a DF83V while it’s currently on sale

I’m trying to be honest with myself - I don’t want to upgrade purely for the sake of upgrading, and I’m not unhappy with my coffee, but I am itching for something different in my setup after 3-4 years. Ideally something that is nicer to use and tastes better. I have no real budget constraints, but can't justify buying a Weber or Option-O Lagom.

A few key questions:

• Would I actually notice a meaningful difference in espresso quality going from DF64P → DF83V?
• Or would SSP burrs in the DF64P get me 90–95% of the way there?
• Does the DF83V significantly improve workflow, retention, and mess compared to the DF64 platform?
• Is the upgrade more about UX and enjoyment, or genuinely noticeable in the cup?

For context:

• I drink mostly milk-based espresso
• Medium roasts
• Single dose workflow
• Not chasing ultra-light clarity shots, more balanced espresso with body and clarity

Would love to hear from people who have:

• Upgraded from DF64 → DF83V
• Installed SSP burrs in a DF64
• Or tried / compared both!

Was it worth it?
