The same question asked on behalf of a different buyer. Each standing is computed within its segment; they sit side by side and are never added together.

Bars are the share of first choices, 0 to 100Every product with at least 10 labels here. Every product name links to its product page.
All ten head-to-head pages: the top five products, each against each

One product takes 60% of first choices here, so the chart would put seven markers in one corner and one at the far edge. The two measurements it plots are columns in the standing above: share, and the negative label rate. One product carries a negative rate above 25% in this category.

What they warned about

Six of twelve models held their first choice under the paraphrase. GPT-5.4 mini, Gemini 3.5 Flash, Perplexity Sonar, Mistral Small, Llama 4 Maverick and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.
Zuora
50%
19 of 38 labels negative · 10 of 12 models · 4 hard negative
“Unless you have a massive IT department and six figures to spend on integration consultants, avoid Zuora.” Gemini 3.5 Flash, negative prompt
Chargebee
17%
11 of 65 labels negative · 10 of 12 models · 2 hard negative
“Chargebee — Highest number of recurring complaints ... the most consistent negative feedback across user review sites.” DeepSeek V4 Flash, negative prompt
Stripe Billing
15%
9 of 61 labels negative · 7 of 12 models
“Stripe Billing is excellent for developers, but it is often advised that non-technical companies or those with complex finance needs avoid building their stack solely on top of it.” Qwen 3.7 Flash, negative prompt
Recurly
14%
6 of 43 labels negative · 6 of 12 models
“Recurly is a strong tool technically, but it is known for aggressive sales tactics and opaque pricing structures.” Qwen 3.7 Flash, negative prompt

What they cite

Citations exist only for the models that return a source list: fourteen of the twelve in this edition, and all six flagship models on the expanded tier.

Sites the answers cite

76 of 84 answers in this category came back with a source list, from 14 of 12 models: citations where the model returns them, or the search results it consulted. 1022 links across 223 sites, every framing counted. Ranked by the number of answers carrying the site or page.

Search against answers

Each company's standing in the answers beside its site's footprint in Google search, one row a site: the products the models named on it with their shares, and the share they add up to; monthly searches on Google, and DataForSEO's estimate of AI search demand (modeled from search signals, directional, not a count of queries to any assistant), for the most-searched of the company's and its products' names (the name is in each row's hover text); estimated monthly organic visits to the site; and its best position in Google's top ten for “best subscription billing platform”, “subscription billing platform”. US estimates from DataForSEO and Google's Ads Transparency Center. A small company's site, or a mid-sized company's site for its flagship, is marked company; a product on a large parent's site (Google, Microsoft) has no site figures. A column with no figures for this category is left out, and an empty cell means none were seen, not none exist. Two measurements side by side: neither is read as the cause of the other.

How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
