My opinion on this matter overall.
My personal experience is that it sucks when modifers stop you from shooting, I hated-hated the game when I first ran into that, but I can't help but feel the currently list telegraphs a close combat army very strongly. On a superficial level, if you take shooty orkz you are building the army around its worst characteristic. The reason why we did that is previous editions was because of how our rules worked and codex creep. We were not especially effective in close combat, while the shoota gave us more options, and at one stage was something of a USP. Now there's a reasonable chance of boyz striking first, S4, Da Jump, the Waagh Banner, Warbosses, Ghazzy, and a number of buffs explcitly about close combat. Orkz are a close combat army again. Everything else is support, or covering fire.
That said, there are still legit reasons to take shooty orkz, just not ones that make them the default choice. Shoota boyz fire as effectively in overwatch as as beakies, and no modifiers apply there, unless I've missed a FAQ. If you are up against meatsheilds, the dakka helps more than the choppy. Grot artillery is very useful, and cheap. Lootas, Tankhunters and Gitz do their job well, if suffering from being really obvious targets.
TLDR: Choppy first, shooty 3rd.
