Reconfiguring Ground wires for 2 panels

Hello everyone!

Question on how to "clean-up" the grounding wires on a recent service upgrade.

My home used to have a 200 amp service, (2) meters feeding (2) 100 amp panels. Upgraded to (1) meter 400 amp service, feeding (2) 200 amp panels now. The home was originally a 2 family, therefore we had a panel and meter for each unit. We converted the space back to a single family, but we were advised to keep the panels separate as the cost to relocate to a single main panel wouldn't be worth the expense.

During the upgrade, the electrian installed new grounding rods (2), which are bonded above ground (see photo). The first panel has a ground running directly from the panel to the grounding rod (black wire in photo). The 2nd panel has a disconnect near the meter, where they went from the grounding bar in the disconnect (green wire in photo) to the other panel's black wire where this was bonded.

I really don't like how this looks, it seems sloopy to me. My thoughts were to re-run the ground wire from the first panel to the grounding rods, exiting below the meter by LB, then conduit down. The second panel I will disregard the current Green wire at the disconnect, and run a new grounding wire directly from the panel, to be bonded to the other panels grounding wire inside the wall (same bonding clamps as currently used) then exiting through the conduit with just the 1 wire. This seems to be essentially the same set-up as what's currently installed with exception to the bonding being done on the interior of the home and being placed in conduit outside.

Is this acceptable? Any other suggestions or ideas to clean this up?

I approved this because the poster is just asking for an opinion, not advocating for doing anything themselves.

My opinion:
Functionality and safety trumps aesthetics in our industry. Aesthetics are not part of the Code requirements, other than a general statement of "neat and workmanlike manner". I see nothing in your pictures that would be considered otherwise. I might have expected to see two ground rods, but I wasn't there to see the ground resistance testing and assuming this was permitted and inspected, it's basically par for the course, in fact it's better than a lot of stuff I have seen.

Thank you Jraef. There are 2 ground rods.

Although functional as is, would another option be to have run #6 from panel A, acorn to each ground rod, then land in panel B in 1 continuous loop?
