Both the Huddersfield and Minisport offerings tend to use own brand, or budget unbranded components, with noisy cone filters, whereas the Minispares kit uses the renowned Maniflow manifold, together with the well developed RC40 exhsust system and the market leading K&N element filter. The minispares kit is therefore arguably a higher quality, more refined kit, I have one on my sprite and wouldn't hesitate to recommend it.
However, If I had the whole market to choose from, I'd actually choose the stage 1 kit offered by Somerford, because it consists of a complete Maniflow system combined with a Maniflow manifold & K&N element. This is what I have fitted to my Mayfair and is the only kit I'd recommend over the minispares one.
