Soup maker or stand mixer? The smarter buy for your kitchen

Display

Neither product is really a display-led appliance, so there’s no screen quality race here in the usual sense. The Ninja HB150UK has a simple control interface built around 10 Auto-iQ programs, which makes it more guided and beginner-friendly. The Kenwood KMX754CR kMix is more old-school, with manual speed control and no cooking presets, so it relies more on the user knowing what they’re doing. Winner: Ninja, because its program-led control is easier and more intuitive for everyday soup, smoothie, and sauce making.

Performance

This is where the products diverge completely. The Ninja is a 1000W blender with a built-in heating element, so it can blend and cook soup in one jug, handle both hot and cold recipes, and tackle everything from smoothies to purees. That makes it brilliant for quick lunches, batch soup prep, and smoothies without needing a separate saucepan. The Kenwood is also 1000W, but that power is aimed at mixing, whisking, and kneading rather than heating or blending. It will outperform the Ninja for cake batters, whisked cream, meringues, and dough thanks to its stand-mixer design and 6 speeds. Winner: tie overall, because the Ninja wins for blending/cooking performance, while the Kenwood wins for baking and dough performance.

Build quality and design

The Kenwood kMix has the stronger premium feel for long-term kitchen use. Stand mixers are built to sit on the worktop, take a beating, and handle heavier mixes, and the kMix range is known for its sturdy metal-bodied styling and classic cream finish. It will look at home in a UK kitchen if you bake regularly and want something that feels substantial. The Ninja is well put together too, with a 1.7L glass jug, tamper, brush, and a heating element built into the base, but it is still a countertop blender rather than a heavy-duty mixer. Winner: Kenwood, for more robust construction and a more premium appliance feel.

Battery life

Neither product is battery powered, so this category doesn’t apply in the usual sense. For practical UK use, it’s more about mains-powered convenience and cable placement on the worktop. Both are 1000W appliances, so you’ll want a decent socket nearby and enough clearance for daily use. Winner: tie.

Price and value for money

The Ninja is £129, while the Kenwood is £219, making the Ninja £90 cheaper. That’s a significant saving, especially when the Ninja also includes hot blending, 10 Auto-iQ programs, a cleaning program, and accessories like the tamper and brush. For most households, the Ninja offers far more functionality per pound because it can replace a soup maker, blender, and some meal-prep tasks in one appliance. The Kenwood is pricier, but you’re paying for a specialist baking machine rather than a multi-function blender. Winner: Ninja, by a clear margin on value.

Game library/features

Again, these aren’t gaming devices, but in terms of feature set the comparison is straightforward. The Ninja’s 10 Auto-iQ programs are the standout feature: they automate common tasks and make the machine feel smarter and more versatile. Its hot-and-cold capability, 1.7L glass jug, built-in heating element, tamper, and cleaning program give it a strong all-round feature package for soups, smoothies, and sauces. The Kenwood’s feature set is narrower but excellent for its purpose: 6 speeds and stand-mixer functionality for mixing, whisking, and kneading. If you bake often, that focused feature set matters. Winner: Ninja for sheer versatility, Kenwood for baking-specific usefulness.

Overall user experience

The Ninja is the easier appliance to recommend for the average buyer because it does more, costs less, and suits busy everyday cooking. It is especially appealing if you want homemade soup, quick smoothies, and low-effort cleaning in one machine. The Kenwood, however, is the better choice for serious bakers who regularly make cakes, pastries, bread dough, and batch bakes. If your kitchen routine is more Mary Berry than meal-prep blender, the kMix will feel like a proper upgrade. Winner: Ninja for most people, Kenwood for dedicated bakers.

Overall summary: the Ninja Foodi Blender & Soup Maker HB150UK is the better buy for most households because it delivers more functions, a lower price, and stronger value. The Kenwood kMix is the specialist choice if baking is your main hobby and you want a sturdy stand mixer that will earn its place on the worktop. For the widest audience, the Ninja wins this head-to-head.
