Boardman or Planet X

So cyclesheme budget of £1K.

Found the Boardman team Carbon, was like oh yea, mix of Tiagra and 105, but seemed ok.

Then Found the Planet X Pro Carbon with Ultegra! Double oh Yea! Waited to many days to press buy…

Then they’ve changed it to a SRAM Rival groupset.

So question is, does the Planet X still out perform the Boardman?
The Planet X frame seems to be a few years old, where as the Boardman looks brand new and lots of talk about how it is constantly refined etc.

What do people think?

How does SRAM Rival ( with WiFLi, 11-32) compare with the Tiagra/105 mix?

Leaning towards the Planet X!
But need help!

Cheers,
Lee
