Should lights on a three-way circuit connect to the switch with the power cable attached?
There are several ways to connect 3 way switches.  I always prefer the 2nd method you posted. There is no &quot;code taping&quot; needed, since all the wires are already the correct color.   The 2nd method is so simple and straightforward:  Power in to one switch, x/3 to the next switch then to the fixtures.   Sometimes it's not practical due to length of runs (takes too much wire), but I'll do it that way every time if possible.
