Exterior wall wooden house: agony of choice

Good evening,

in search of a timber house builder, I have now been able to narrow it down to 2 favorites. Since they differ little in terms of appearance (facade, structure, etc...), I am now examining which facade construction is better. Because this is where the two companies definitely differ.

Company 1 (from outside to inside):

[*]Log beam 70 mm
[*]20 mm spacers (ventilation)
[*]Diffusion-open wind barrier
[*]200 mm stud framework with 200 mm insulation
[*]Vapor barrier foil including sealing
[*]60 mm installation level made of KVH with 60 mm insulation
[*]12 mm OSB board
[*]12 mm gypsum board

Company 2 (from outside to inside)

[*]Wood lathing 28.5 mm
[*]30 mm spacers (ventilation)
[*]16 mm wood fiber insulation board
[*]200 mm stud framework with 200 mm insulation
[*]15 mm OSB board
[*]60 mm installation level made of KVH with 60 mm insulation
[*]15 mm OSB board
[*]12.5 mm gypsum board

Basically, the two constructions differ in that Company 1 uses foils (diffusion-open – brand name omitted) as wind and vapor barriers. Company 2 uses a 16 mm wood fiber insulation board and a 15 mm OSB board in the same place. According to the company, this is also diffusion-open. Since I am a layman, it is difficult for me to assess the comparison of both constructions.

Is one of the two construction types to be advised against? Are there relevant advantages or disadvantages?

According to forum rules, I do not name the builders and have omitted the brand names of the components. If necessary, I can upload photos of the constructions.

Thank you very much

Company 2 has the higher-quality wall construction, which is today also standard in timber house construction (... should be ...). The use of vapor retarder, vapor barrier, and wind barrier films should be avoided if possible. The films age/brittle, etc., despite the theoretically guaranteed service life of up to 50 years. Furthermore, damage inevitably occurs during installation, which then goes unnoticed. This makes leaks inevitable. The construction with wood fiber insulation board/OSB is significantly more robust. The OSB board must be sealed airtight at the joints with an approved tape. The transitions to other components must also be worked out in this way.
