That's an interesting question . How to choose ?
When I was aircraft engineering , the most used tool for me was the long handled speed brace , undid thousands of those blasted 'Phillips ' screws over the years . Hated that one though . Got really sick of panel removal and refitment .
Got a really nice wee Snapon 3/8" drive ratchet with a short handle , just fits in my hand with nothing to spare . Makes for easy fast action and is delightful quality.
Think the tool I had the most fun on though was the Bridgeport milling machine . I could make anything on that , and often did !. Digital readout helped lots

Used it when I was doing prototype engineering for a 2way radio Co. It was great learning to do compound curves just using the handles .
