Objection: "We're already using [competitor]"

Help me respond to "we already use {{competitor}}" without being defensive or trashing them.

Context:
- My product: {{your product + key strengths}}
- Their setup: {{competitor they use, what we know about it}}
- Where we genuinely outperform: {{2-3 specific advantages with proof}}

Give me:
1. **A 2-sentence response** that acknowledges their choice without surrender
2. **Three follow-up questions** that surface dissatisfaction without leading the witness
3. **The pivot** — once they share friction, how do I bridge to our advantage without sounding rehearsed?
4. **What NOT to say** — common SDR moves that backfire here

Be honest if our advantage is marginal — don't manufacture differentiation.
