EY-P D2 (Tech/Software PE Value Creation) vs Strategy& Manager — lateral move rationale?

Would appreciate perspectives from the community on a potential lateral move.

Current role:
Manager at Strategy& (enterprise / functional strategy)
Comp is broadly similar to offer below
Strong network, solid trajectory to SM, but work is fairly generalist and increasingly focused on operating model — not an area I’m particularly interested in long term

Offer:
EY-Parthenon, Director (internal manager role)
$210K base + $25K signing + 0–40% bonus
Team: Tech / Software PE Value Creation (falls under software strategy group)
Work focused on PE funds + portfolio companies, primarily post-acquisition value creation (vs heavy DD)

Rationale for considering the move:
• Opportunity to specialize in software + PE value creation vs continuing as a generalist
• Newer group → potential for faster progression if performance is strong
• More tangible, execution-oriented work vs high-level operating model strategy
• Exposure to PE clients and potential path to portfolio company / PE operating roles
• Team positioning seems less DD-heavy vs typical PE strategy groups (based on conversations)

Reasons to stay:
• Strong existing network and brand at Strategy&
• Clear and relatively de-risked path to SM
• Comparable compensation
• Known quantity in terms of staffing, culture, and performance expectations

Would love to get perspectives on:
• Does this rationale for a lateral move hold up?
• How valuable is the EY-P software PE value creation platform/ software strategy group vs staying broader at Strategy&?
• Realistically, how strong is the PE / portco exit opportunity from this type of group?
• Any risks I might be underweighting (e.g., progression, staffing model, deal flow, type of work)?

Appreciate any thoughts.
