Personally, I recommend against kits. Almost universally, the press itself is the only enduring piece from a kit which enjoys continued use as a reloader progresses. I know some Reloaders do continue to use the hand trimming tools, or trickle into a beam scale, but most reloaders, an overwhelming majority, learn their way through the process within 6 months and end up replacing almost every component from the kit. Buying twice is rarely less expensive than buying once. Frankly, many, many reloaders quickly realize their reloading volume can’t be sustained by a single stage press, and end up replacing that too.
Of the gear included in both kits, the RCBS kit is the better value - meaning more gear for less money, but as mentioned above, the extra gear only has value if you’re going to use it.
As an example - I started with a Lee kit 25 years ago. The only piece I still use is the press - which is ONLY used as a universal decapping press, and has not made ammunition for almost 20 of those 25 years.
