Amazon DynamoDB vs Redis
One of fourteen models named Amazon DynamoDB first on the direct prompt; zero named Redis. Both were named by all fourteen models and Amazon DynamoDB carries 67 labels and Redis 55, so the shares are not directly comparable.
Named in three categories this edition.
Named in four categories this edition.
First-choice share11%2%Of first choices across the direct, paraphrase, budget and scale prompts, 0 to 100.

The two percentage rows are drawn on one 0 to 100 track, Amazon DynamoDB reading right to left. Rank and label count are printed, not drawn.MongoDB was named alongside these two in fourteen of the fourteen direct answers. MongoDB vs Amazon DynamoDB · MongoDB vs Redis · Amazon DynamoDB vs Couchbase
Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen models, for a mid-market B2B company; rank is within the category; every quote names the model and the prompt it came from. Both figures come from the nosql databases page.
By framing
How many of the fourteen models made each the first choice, per way of asking, and how many argued against it.

Bold names in an answer are the products the judge labeled a first choice; a model naming several gives each of them that label. The full answer text for every row is in the record.

“Avoid DynamoDB unless you are deeply invested in AWS” GLM 4.7 FlashX · paraphrase prompt · hard negative
“AWS guidance says to avoid large items, reads on non-key attributes, and scans, which means it can be a poor fit if your access pattern is not key-centric” Perplexity Sonar · negative prompt · soft negative

What the models said about Redis
Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Six of seven in this category shown.
“Redis is extremely fast but should be used with caution for data that needs to persist on disk or for applications requiring complex queries” Mistral Small · negative prompt · soft negative
“Cautious when: Using it as a primary database rather than a cache — it's an in-memory store, and data durability can be a concern.” DeepSeek V4 Flash · negative prompt · soft negative
“early versions lacked auth. Redis 7+ is solid; use ACLs and avoid as a primary durable store unless clustered with persistence.” Grok 4.1 Fast · negative prompt · soft negative
“Redis is the most popular and versatile key-value store... ideal for mid-sized B2B applications” Mistral Small · paraphrase prompt · first choice
“Redis receiving the highest rating of 8.9 among the leaders” Claude Haiku 4.5 · comparative prompt · first choice
