Rules-lawyering drama queen but not a munchkin
That's not a bright side. That is a cop out. Part of the essence, the feel of the sorcerer is the stability of character identity given by a fixed set of spells known. Sorcerer magic is not an active choice, and overall not an ongoing choice. Having to prepare spells is an active ongoing choice, and opting out of it is a betrayal of the party because then you are not contributing fully to the party and the party suffers because of it. The possibility of full access to wizard spells is tempting, but I also expect them to suddenly curtail it for no reason. Like dragon sorcerers only get evocation, divine souls only get abjuration and so on. The more mechanics sorcerers and wizards have in common, the more the sorcerer will suffer.On the bright side, the only 5e shortcoming of being a Sorcerer used to be having the smallest number of known spells of every full caster, and now they will know A LOT. Except that, if they go with the currently rumored "four schools of magic only", the Wizard will of course know twice as many.
