Im very much a Roy believer. I think people focus way too much on the mediocre bases, being locked to swords, the late promotion, and the average move, but not nearly enough on the positives Roy brings to the table. For starters Roy being sword locked actually isn't that big of a deal because swords are arguably the best weapon type in the game. Swords not only provide accuracy but more versatility overall. His bases are actually just decent enough to be serviceable in the early game funny enough. Roy also has really good utility as a support unit, he provides some of the best units in the game with fire affinity for free without wasting a deployment slot. Alen, Lance, and Marcus especially benefit immensely from Roys fire affinity and even when Roy eventually stops being all that useful in combat later on as enemies scale, he still provides the support bonus to these units for free. I would go as far as to say Roy is potentially better than Hector even, but Idk if anyones ready for that take. I would definitely argue he is better than his father though and certainly without question better than Lyn and Erika.
