Air tools if you’re on a budget. I use a dewalt 20v 1/4 impact driver for most everything on the Jeep (socket adapters) and can still use it around the house with other bits. For the big shit grab the 1/2” air impact. That’s the one complaint I have about the cordless impacts, they’re too damn big and bulky and often can’t fit where I want them air impact is far more compact.

I agree that the 1/2" Milwaukee is big, but I have an assortment of extensions, some with the angled ends, and the better wobble adapters. I was able to reach 90% of bolts on my engine swap that way.
Even the upper bell housing bolts, with about 3' of extension and a couple of wobbles.
Yeah I don't mind using them for tear down but I also feel the same about feeling things when I assemble. I mostly wanted to power stuff to make taking apart faster, so I went ahead and bought it this morning. I don't have any power/air tools so I figured if I was going to go in for them I wanted to make sure I started off right. Consensus was Milwaukee, so that is where I went.
With practice and experience, you learn how hard the tool is hitting.
I will hit things with the torque wrench to check, and most times I get less than 1/8 turn to click. If you click before it turns, you ha e overtightened, so practice stopping the impact soon enough to be close.
While not fool proof, it is a real time saver, especially for trail repairs.
Keep in mind, an impact gun, either air or electric, does not make max torque right away. It hits a point, then ramps up the longer you hold the trigger, as more blows make higher torque.
There are some good testing videos on YouTube that graph the torque to the amount of time. When you understand the relationship, you can get the most out of your tools, without twisting every bolt.
The great thing about the 1/4" impact driver, in my opinion, is that it maxes out under 26 ft lbs. You can use it on small bolts without fear of over tightening, but still doing final torque with a torque wrench.
