The short version

Each has a real cost: i2c developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.; Rutter a unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
They diverge on capability: i2c covers Configurable product engine, Rutter covers Accounting and ERP.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

i2c

Developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.
Implementations lean on i2c or partner professional services, so timelines and costs are set by a services queue rather than by your own engineering speed.
Pricing is per active card and per transaction with monthly minimums, none of it published, so comparing bids requires modelling your own portfolio carefully.
Configuration flexibility means product behaviour lives in platform settings rather than in your repository, which complicates version control, testing and audit trails.
As a private company with a broad global footprint, regional support depth is uneven, and a programme in a smaller market may get thinner service than a flagship account.

Rutter

A unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
Write operations into accounting systems are where these products break, because each system validates differently, and a rejected journal entry surfaces as a support ticket against you rather than against the ERP.
No pricing is published beyond a sandbox trial, so cost cannot be compared against alternatives without a sales process, and pricing tends to scale with connected accounts.
QuickBooks Desktop and other on-premises systems require a local connector or hosted agent, which introduces installation steps your customers must complete and support burden you inherit.
Sync freshness varies by platform and by customer authorisation state, so a product promising near real-time figures will find some connections update far less often than the marketing implies.

Answered from the vendors’ own pages

i2c: Does i2c issue the cards itself?

No. It processes; issuance sits with a bank or licensed issuer, and in most markets you need that relationship separately.

Rutter: Does Rutter support QuickBooks Desktop?

Yes, which distinguishes it from unified APIs that only cover cloud accounting, and matters because many small businesses still run it.

i2c: Can it handle revolving credit?

Yes. Credit, instalments and buy-now-pay-later sit on the same platform as debit and prepaid, which is unusual among modern processors.

Rutter: Can Rutter write data back?

Yes. Invoices, bills and journal entries can be pushed into supported accounting systems, not only read.

i2c: Is it self-serve?

No. Expect a configuration-led implementation with professional services rather than signing up and calling an API.

Rutter: Is there a free tier?

There is a thirty day sandbox trial with test data. Production access requires a paid plan with quoted pricing.

Rutter: What if the unified model lacks a field I need?

Rutter supports passthrough requests to the underlying platform API, though using them reintroduces platform-specific code.
