The list works well, and with assault marines as troops it's very unique. With the exception of Eldar (guardian jetbikes) no-one can hold a candle to the Blood Angels for speed.
The .pdf isn't the be-all and end-all; there will (supposedly) be a proper codex at some point, but since the Blood Angels codex was so adrift and no miniatures were released, it seems fair enough.
The main downsides, as noted, are the wargear and the price of assault marines. Storm shields, digital weapons, et al, are nice tricks but it's the core units which suffer, especially the assault marines, who got a ridiculous discount in the new codex.
That said, the Veteran Assault Squad are, as noted so much cheaper than Vanguard it's not funny, the Death Company are unutterably nails (as ever) and the Blood Angels special characters kick codex tail. This is Dante. Yes, those special rules do what you thought they said. Nice, eh?
Even the regular characters are nice - ok, no relic blade, but paired lightning claws and a combiweapon is a nice trick, and apparently every Company Captain is as good a strategist as the Blue-Armoured Boys Blue-Eyed Boy, Sicarius, getting Rites of Battle instead of a normally useless WS upgrade that only matters when duelling with generals rather than squads..
It'll be interesting to see what they eventually do with them. One big question would be should the Death Company be made an option - as in really an option, not 'you've paid for them but don't have to use them' - as this gets in the way of anyone wanting to use the codex to produce an assault army that isn't genetically psychotic (say, someone's 8th company?).
