If you've spent ten minutes in any placement community, you've seen the same three sheets recommended on loop: Striver's A2Z, Love Babbar's 450, and the Apna College set. They overlap heavily — but they're built on different philosophies, and the "best" one depends on where you are right now.

SUITS doesn't pick a winner — it lets you track all three in one place and reorders them around your target role. But if you're choosing one to anchor on, here's the honest breakdown.

Striver A2Z — the structured curriculum

A2Z is less a "sheet" and more a course. It walks from "Learn the basics" through to advanced topics in a deliberate dependency order, with each step gated behind the last. Roughly 450+ problems across clearly defined steps.

• Best for: Beginners who want a path, not a pile. The ordering removes "what next?" paralysis.
• Watch out: It's long. Finishing A2Z is a multi-month commitment — pace yourself or you'll stall at step 7.

Love Babbar 450 — the breadth grind

The 450 is the classic topic-bucketed checklist: 450 problems grouped by topic (arrays, matrix, strings, … graphs, DP). It's flat — no enforced order, no hand-holding — which is its strength and its weakness.

• Best for: Intermediate students who already know the basics and want broad coverage fast.
• Watch out: The flat structure means it's easy to over-index on early topics (arrays) and never reach graphs/DP, which is where interviews are won.

Apna College — the gentle on-ramp

The Apna College set is the most beginner-friendly of the three, tightly coupled to its free video lectures. Smaller and more curated, it prioritises understanding over volume.

• Best for: Absolute beginners who learn best alongside video and want momentum early.
• Watch out: You'll outgrow it. Treat it as the on-ramp, then graduate to A2Z or the 450 for depth.

Stop sheet-hopping

The real trap isn't picking the "wrong" sheet — it's restarting. Switching sheets resets your progress bar to zero and feels productive while accomplishing nothing. Pick one, track it honestly, and let your target role decide the order. That's exactly what SUITS automates: one progress model across all three sheets, reordered by role, so changing your mind doesn't cost you your streak.
