Don't bother with the hacking one if you're willing to use Valentine as your companion. He can hack any terminal. Just command him to do it.
Also, there are /A LOT/ more companions out there than I was lead to believe. I was using the dog for 10+ hours and then Danse became available... I used valentine too. So far I've used Paladin Danse a lot because he's /really good/ at killing everything. The dog was borderline useless. Good for picking up items that you might miss, maybe. But really not that worthwhile otherwise. He just doesn't pack any damage or live long like Danse can.
I might go back to Valentine though because of the hacking thing. Hard to say. Danse is so freaking OP in comparison. I literally don't have to ever attack anything. I can stay back under cover and he'll just clear entire levels like it's nothing.
One thing that bothers me about this game though is the ammo. I am constantly running out. I don't do VATS enough because it takes so much time for the animations. I'm also better at getting headshots on my own than VATS is. :/
One of the perks you can get tells you more detailed info about guys when you're in VATS so you'll be able to judge whether the gun you're using makes any sense. (Gamma gun does next to nothing against super mutants, for instance)
I run n gun and only ran out of 10mm ammo as I though the pistol was unlimited. It was actually unlimited in the sense it doesn't need a reload. In 20hrs of playing (on easy, too lazy) I already have a few hundred .45 and .308 and 12 gauge ammo plus any .38 I find I sell and replenish what I need. .38 is useless as you progress. 400 .38 rounds isn't great when you need 10 rounds to knock something down, whilst a .45 takes 2 or 3 at best.
The pistol perk is very very useful as a basic 10mm with some tinkering can slam up past 50 for a base damage each round. Plus the rifle perk(s). You need to manage different weapons. I rotate between a .45 rifle, a 10mm pistol, a .308 pistol and a double barrel shotgun. Any ammo I don't use gets scrapped and sold for top ups if raiders/environment doesn't provide.
Don't like companions, I use the dog (for now) as a bullet sponge as it can't die and occasionally as a loot mule.
