I like it. Its very helpful as when you build SM you use tweezers anyway, the parts are so small. Now, you have an option to ID the parts instead of burning your eyes trying to read those unreadable markings. Complete accuracy is not used in that mode, but the parts all look alike so as you pick them, you can confirm what they are.
I prefer not built with SM because I'm not a pro EE. But speed is everything, from design to prototype and getting the device out there and working, so I prefer something I can see easily and use my hands with, which is typically DIP and SIP sized. But the final device is best as small and power frugal as possible, and a good case, that is MILSPEC shock and water proof, is always a plus.
