Wide shorter board or longer board for these wavetypes

I have been surfing for 3 months, still have trouble popping up and with stability (strength/flexibility issues) so my progress is going slow, slower then my friends and I also surf only 1-2 a week for 2 hours.
I surf the North Sea in the Netherlands, which has steep and hollow waves, mostly wind swell like this: https://www.wannasurf.com/spot/Europe/N ... how&page=7
Now I have tested 2 boards I might want to buy
Board 1: Very wide but short with 7'0 x 25 3/8 x 3 85 liter. Much easier to pop up, more stable, seem to not pearl as much due too shorter size, easier to turtle roll big whitewash (we have a shitton of whitewash). This board feels better overall then board 2, but turns more difficult? Picture of the board : https://pukassurf.com/wp-content/upload ... ards26.jpg
Board 2: Very long with 8'6 x 23 x3 x 90 liter: Despite being longer, its more difficult for me to pop up, more difficult to stay stable/more pearling, but seems to turn easier?
So I guess I have 2 questions
1. Which board would be able to turn easier so I can practice going down the line, or do you guys think the difference between the 2 in turning is almost negligible?
2. Looking at the type of waves we have, which board would you guys suggest?
