As an electronics tech I think each person should decide what works best for them themselves...
An electronics tech would not suggest that someone decide what works best for them, rather he/she would recommend whatis thesafest mostreliable and electrically "correct"product/method for the particular application.
Oh and all that wiring in your picture, harnesses etc, very unnecessary for a series connection, Bullets simplify and improve immensly over cheap HXT T plugs. Any tech will know resistance across additional lengths of wire coupled with masses of extra plugs just robs the system of power.
