Don't think Ares will be that good (hopefully I'll be pleasantly surprised), but I do like how the aesthetic of the Grid changes depending on who made it.
The ENCOM Grid is low-poly and very simple, both an indication of its age, but also makes sense given that this one was likely the only one created by an artificial intelligence, the MCP.
The Tron System Grid is full of sleek shapes and glowing lines, looking vastly different - Kevin Flynn created this Grid as a mirror of the real world, and probably would have taken into account aesthetic considerations.
The Arq Grid is very similar, and this makes sense - it was also created by Kevin, and thus shares many of the aesthetic choices. And yet, it's also evolved on its own, with elements not seen in the Tron System Grid - much like the ISOs that inhabit it.
The Dillinger Systems Grid clearly takes elements from both the Tron System Grid and the ENCOM Grid, likely being a copy of the Tron System Grid created by the ones who made the MCP. It's similar to the latter, but harsher, and has Dillinger's branding all over it if Ares's triangular Identity Disc being engraved with their name means anything - something I suspect is because this Grid was made for a profitable purpose (perhaps military?)
