£300, well most of this is going to be subjective & depend entirely on the views of the poster.
What I will say is that
1. Praxis Works are a high end manufacturer of cranks & chain rings, often used by racers & the wealthy to upgrade even Shimano Dura Ace & Campag Record cranks.
These will not be Praxis top of the range though.
2. I have heard of people complain about FSA gossamer before now, not often, but a google will confirm this.
I think
@BigonaBianchi chainset broke in Cyprus (maybe it wasn't FSA) & I believe he had put many hard miles on that chainset too, so not really an indication towards poor quality, more maybe age & fatigue (& that's just BOAB)
Fulcram wheels are good quality & likely lighter & better quality than Axis, which helps more than anything else mentioned.
Fulcrum supply wheels to many bike manufacturers with special decals & model names, including Cube & Bianchi for example, these are re-badged standard line models & are as correctly pointed out elsewhere owned by Campagnolo.
Shimano 105 brakes, very good quality, but I couldn't say if they are better than the Axis as I have never tried Axis brakes.
You might argue that the higher spec bike will be easier to sell or retain more of it's value come re-sale time, hard to know that though.
All things considered, I would go for the Elite *upgraded* model, but I am a closet brand snob.
