Absolutely correct, results should be your guide.
Blanket statements and generalizations in favour of budget soaps simply evidence lack of understanding about soap composition and differing costs and the effects of different compounds in soaps. Soap formulas are not a done deal, the chemistry evolves.
Blanket statements are damaging and ignorant in that they make assertions based on dated, flawed baselines and this is compounded by lacking any direct experience of current or even premium priced soaps. Wet shaving soaps evolve and are refined constantly, budget commercial soaps face an entirely different economy of scale than artisan soaps that have considered and specialist design and composition. What was considered fantastic 10 years ago still may be good, but newer compositions and advances made in that decade afford a whole range of soaps that are unquestionably superior, but that remain untried due to reflexive dogma and a refusal to revise understanding based on new evidence and products.
Soap "technology"? I don't buy it, sorry. I go on results - which are subjective, but never have I tried an expensive soap that would noticeably outperform a good budget one. Tabac, Proraso, Speick, Cella... not 'cheap' just inexpensive and no marketing-driven scent names.
I have used Barristers and some other forgotten boutique names and they were very pleasant, but not noticeably better in any way. Neither did they last long either, disappearing faster than any of the staples mentioned.
If your technique is good and consistent, then the quality of your lather will be too.
