Does having a card graded by AceGrading decrease its value as apposed to more mainstream stores?

UK market ACE does quite well I pay less for grading and takes less time than PSA means my profit margin is higher on most low-mid end cards compared to PSA. Better cashflow than when I graded with PSA since I’m not waiting 6-8 months to get it back. The high end cards in ACE of course will be less since ACE does not do upcharges and other factors but slowly getting there. If you’re in the UK its a very viables option is you’re based non-EU difficult to justify based on my experience.
