The pension wins on the way in (tax relief on contributions) but the ISA wins on the way out (tax-free withdrawals). At most income levels, the optimal strategy is to use both — pension first to the employer match, then ISA, then pension again.
What matters most when comparing
When comparing financial products and platforms, focus on: total annual charges (platform fee plus underlying fund costs), the range of investments or features available, regulatory protection (FSCS coverage), and ease of use and customer service quality. A 0.5% charge difference on a £50,000 portfolio costs £250/year and compounds significantly over a 20-year horizon.
