We will have to agree to disagree on this one! Haha.
For me, Hedi’s arrival at Celine brought an inevitable downgrading and cheapening of the brand. They sacrificed prestige for sales, as most of the other LVMH brands did also. The brand reputation peaked with Phoebe Philo : great design, no logo's, and limited distribution.
The thing is once a brand starts to produce things like sweatshirts, t-shirts, etc etc with logos everywhere - it's the beginning of the end in terms of maintaining prestige. Hedi may put a lot of effort into creating a halo effect around the runway collections and "Haute Couture" lines, but at the end of the day, Celine is selling cheap merch with the logo on it and/or the words CELINE emblazoned on it. How else do you think he got to 2 or 3 billion in sales? By selling exquisite white shirts and tweed blazers? LOL I don't think so. It's by selling the cheapest of the cheap things in the brand that the masses wear (and often with no sense of style). The amount of people I see wearing all those Celine t-shirts is so off-putting. It's no different than how Riccardo ruined Burberry by putting that cheap TB logo on everything.
To be honest the only LVMH brand really that has maintained its aura is Loro Piana. Maybe Loewe too, but I see they are doing a lot of logo's now too. Outside of LVMH, I would consider Phoebe Philo and The Row to be more prestigious than Celine for example.
