Best grout and Silicon that money can buy

[mackstar]

I'm getting some repair work done in a bathroom covered by my home insurance, they are picking up the costs and have asked me exactly which brand and type of grout and Silicon I want. Seeing as they're covering the cost, I want to pick what is the best grout and Silicon (within reason) that money can buy. I know this can be a little subjective but if I get a few suggestions here and pick the one that comes up the most then I'm sure I can't go that wrong.

Someone I spoke to recentlky suggested Bal Micromax for both sealant and grout. Is this a good suggestion?

Kerakoll fugalite bio is the bullet proof option

The new professional epoxy tile grout in A+B format twin tubes is superior to anything ive seen or used in 25 years xp
However most tilers will never have used it before , so as for suggestions cant see there being very many
