Trying to pick a new kitchen tool is hard. I spent weeks looking at the Ninja SS201 vs SS351 to see which one is best. You want a great smoothie blender that works fast. A good countertop blender should not waste your time on a busy morning. I tested both of them side by side. Here is what I learned from real use.
Ninja SS201 Review

The SS201 is a big and strong machine. It sits on the counter and does heavy work. I used it mostly for family meals and big drinks. It feels solid and holds a lot.
Pros and Cons
It is great for big jobs, but it lacks small cups. Here is what I liked and hated.
| Pros | Cons |
| Huge blender jar | No personal cups |
| Fast ice crushing blender | Very loud motor |
| Great for big batches | Hard to clean sharp blades |
Real Experience After Months of Use
I used this daily for a post-workout drink. The huge blender jar makes smooth liquid fast. It crushes frozen fruit and ice with no problem. But, the motor is very loud. It shakes the counter a bit. Making a single protein shake in a giant pitcher feels silly.

The lid fits tight, which gives me relief. I always rinsed right after use to keep the blades clean. Pouring is very easy. It takes up a lot of space. It is a very basic machine.
Recommendation
Buy this if you cook for a big family. Skip it if you just want a quick drink for one person.
Ninja SS351 Review
The SS351 comes with extra cups and bowls. It is a full system. I loved having more options for my morning drinks. It feels like three machines in one.

Pros and Cons
This high speed blender is a joy to use, but it has parts to store. Here is the breakdown.
| Pros | Cons |
| Great personal blender | Takes up lots of storage space |
| Perfect for a thick shake | Motor is still very loud |
| Good nut butter blender | More parts to clean |
Real Experience After Months of Use
I used it daily for a quick breakfast. I often skipped presets and just used the pulse setting. The small cups are perfect for a fast drink. I could make a very thick shake with no chunks. The built-in tamper in the bowl was a nice surprise.

It makes the best smoothie texture I have seen. Making peanut butter was easy. I just had some frustration finding space for all the parts. It does not make warm soup, but cold drinks are perfect. I felt great satisfaction with my drinks.
Recommendation
Buy this if you love thick bowls and personal shakes. Skip it if you hate washing lots of parts.
