phutchins: Is the DRM free really that useful that many are okay with delay patches (and no show of concern by GOG)?
Yes, for me it is. Since I normally play (single-player) games long after their release, I don't mind if updates are delayed somewhat,
as long as they appear on GOG at some point. For instance, at the moment I am playing Fallout Tactics (originally released in 2001 IIRC), it is not like there are some pending updates for it.
Also, for some less important or Steam-specific updates, I don't necessarily mind if the GOG version is missing it altogether. Important updates are... important. Similarly, I usually don't mind if the GOG version is missing the multiplayer part or with some games a level editor or such, as I don't see myself using those features in 99% of the games anyway, I just want to play the single-player campaign and that's it.
For now I don't use the Galaxy client at all, i play my GOG games only using the offline installers. I might install Galaxy (again) at some point if I get interested in some multiplayer game or want to play some in-development game that receives updates frequently.
phutchins: I rarely have any DRM problems in my many Steam\EA games. I buy, install and click game to run.
For me it is more about whether you care that you can continue playing your games even after the store/service closes its doors permanently. Like Desura and DotEmu closed their doors, if their games had not been DRM-free but require a specific Desura or DotEmu client to play them onlline, then all those games people have bought from those services would now be unusable. But since they are DRM-free, I can still install and play my DotEmu games just fine, which I've downloaded from the service a long time ago.
You might claim that Steam is not going to close down ever, in which case you are lying. Yes it will also close doors at some point, the only question is when. So will GOG. The way Microsoft is pushing its own Windows Store in Windows 10, it might happen much sooner than you think. Maybe in the future 99% of Windows 10 gamers will buy all their games from the Windows Store because it is the default store, which doesn't leave much of business for any 3rd party stores, Steam included.
Of course, if you don't mind that your games will become unplayanle the minute the store/service closes, that is fine too I guess. I rather continue playing my games even after that point, like my DotEmu games right now.
For the record, I have 467 games also on Steam, but I definitely prefer buying my games on GOG (where I have currently 1392 games). Admittedly, 90% of my Steam games are not bought through Steam, but been activated from Humble Bundles (usually I bought a bundle for Android or DRM-free games, but also activated the Steam keys included in the bundle, because reasons).
phutchins: Do other games have there patches delayed by weeks too, I have seen similiar comments in a few forums. Is this the exception or rule? Whats the longest wait you been subjected too?
Someone is keeping a list of games that have missing patches or other features (like no German language or Linux version or whatever, in case those are important to you), or even if the author feels GOG customers have to pay too much for the game, compared to a cheaper Steam version:

I haven't bought (nor played) Ashes of the Singularity yet as it seems it is still receiving DLCs, I don't like buying my games in tiny parts (separate DLCs). I rather wait until they have released everything for the game and then buy it all in a bundle.
