Quintana Roo PR6 2016 or Fuji Norcom 2018

Dear all
I am looking for a dedicated tri bike and I have found these two used, at prices around 2400 USD (QR PR6) and 2150 USD (Fuji).
Both appear to be in my size - around 56cm frame (I am 187cm tall). Both are in very good/pristine condition and have seen little use.
On paper, both are similar: Di2 and with deep section wheels, rim brakes. I have a pedal power meter already. As stated, The QR is slightly more expensive but comes with a spare set of training wheels which I don’t really need as I already have a spare set.
Both are stock, except the Fuji has risers intalled for the arms.
Any strong reasons to choose one over the other? I’d love to hear your opinions.
I am a decent swimmer, experienced cyclist and runner, have competed in two triathlons and plan to do many more before I grow too old/busy.

I also looked at buying a never-used, 2016-model bike with mechanical gearing and training/semi-aero wheels at around 1,000 USD. But I can afford the expensive bikes, they’ll have higher resale value and it is very hilly where I live and I have to “commute” through traffic to get to any good riding roads, so I think Di2 would be valuable to me.

I would go for QR because they have good support for parts as PRsix/PRFive rim brake bikes were still available to purchase new in 2022/23. Also better resale value than Fuji. The Fuji Norcom also has aero brake calipers and like Giant Trinity, are a pain to adjust. I considered Fuji Norcom too while purchasing and came across this video which swayed me away

Just be mindful that QR sizing runs large. A 54 is a 56 in other brands. I am 6’0” and have a 54, which is the proper size for me.

Thanks for the comments.
I hope the QR sizing should work out. I’m around 6ft2in. I had not thought about parts availability. I read somewhere that the Fuji has a pretty “stock” front end which should make it easier to find parts for?
I had also assumed resale value would be about the same. I think there are more Fuji bikes than QRs in Norway where I live, but it’s a good point that the PR6 rim brake was in production more recently.
