Tax treatment, and why it rarely decides this
Both sides carry a legitimate deduction, so tax treatment is a tiebreaker rather than the deciding factor.
With financing, qualifying equipment may be eligible for a Section 179 deduction or bonus depreciation, which can pull a large deduction into the first year, and the interest portion of your payments is deductible as well. That front-loads the benefit.
With leasing, the payments are generally deductible in full as an ordinary business expense. The treatment is simpler and spreads evenly across the term rather than concentrating up front.
Which is better depends on your entity structure, your taxable income this year, and the equipment category. Deduction limits and bonus depreciation percentages also change with tax law, so confirm the current-year rules with your CPA rather than with a vendor's sales sheet.
