Both are interesting choices and have good features.
The salmon dial of 5124 is unusual in a very good way whereas the black dial of the 5026 looks very powerful !
Personally I prefer the 5124 because the dial is more balanced vs the off-center subdial of the 5026. Furthermore, the gondolo would enable you to create a Patek collection theme of shaped watches along with 5098R.
Best of luck with your decision and remember to post wristshots and a review !
