starting my 2015 vvt hemi journey

I won't get in a "pissing match" with you over which one is better either, I have no experience with either one! From a "budget standpoint" though, Holley shows their kit at $1899.95, as opposed to your quote of $2300 from Hotwire Auto. I'm just pointing out what you said and what Holley shows on their website,
Holley EFI 550-1424 Holley EFI Terminator X Max - 2013+ Gen III HEMI
They've updated their pricing. It used to be that much for just the computer. Then you had to pay for all the wiring separately.
