What is more preferable: scrolling depth or a convenient gallery on the photographer's website?

Question

Search Engine Optimization

Good afternoon.
Subject: photographer's site
Age: 0
Incoming keyword in the domain: yes
A small dilemma here is the following. There is an option to submit a series of photos of the same subject in a row - to get the depth of the scroll.

The second option: a more user-friendly gallery in two rows with the ability to click (full screen).

There is an idea here that after switching to fullscreen, the user will simply click the forward button, and 100 clicks using this method is not the same as scrolling depth by 100 photos with a height of 600 pixels.
A little offtopic:
If you turn to an SEO office - so all the "brilliant" ideas there boil down to "creating a PBN grid for a promoted site" and such childhood as the depth of the scroll is simply not a subject for making money there;)
Of the other amusements, this is "the need to purchase links from the same region that you are targeting."
In general - a lot of different tales and not so much.
Where did the idea about the depth scroll from.
You take a couple of sites from Google search results - you look at them even without SEO services, just through site: www.krutojfotograf.com in the same Google. You get their indexed pages. It is a mistake to believe that there are 15 maximum of them. To get more organizational transitions, they created about 150-200 landings for weakly competitive requests.
Everywhere there is the same page with the necessary nausea of ​​the keywords and the transition to the gallery or to the contact form.
By this simple method - as a result, you find two sites that confidently get the top 5 in 20-30 European cities (when searching in English).
Their commonality is just in the submission of a portfolio - these are pictures in a row, and scroll down for yourself from 5000 pixels.
It is clear that this is not a key feature for getting into the top. But this is the depth of the scroll ...
The rule of good form here (in terms of behavioral) is to finish one gallery and in the footer there will be three more to choose from. Which increases the number of clicks and the time spent on the site.
Another offtopic
After analyzing the sites that did something in order to be in the top, you understand that the "sites for photographers" from GophotoWeb aka Vigbo are just a beautiful gallery without the possibility of growth in principle.
Question: what gallery and submission method would YOU choose for a WP site?
